How do geologists classify sedimentary rock
WebWhen a rock forms (either igneous or sedimentary), magnetic minerals align with the Earth's magnetic field at the time. Because geologists have good constraints on the timing of past magnetic polarity reversals, they can use these to correlate rock units to a numeric age, as well as correlating rock units to each other.

WebGeologists classify the rocks of earth’s crust in one of three categories — igneous metamorphic or sedimentary — based on how the rock was created. Each type of rock has its own unique characteristics: Igneous: Igneous rocks form from the cooling of melted rock (either lava or magma) into solid form.
WebSedimentary rock is classified into two main categories: clastic and chemical. Clastic or detrital sedimentary rocks are made from pieces of bedrock, sediment, derived primarily by mechanical weathering. Clastic rocks may also include chemically weathered sediment. Clastic rocks are classified by grain shape, grain size, and sorting. WebSedimentary rocks are formed from pre-existing rocks or pieces of once-living organisms. They form from deposits that accumulate on the Earth's surface. Sedimentary rocks often have distinctive layering or bedding.
